' SPECIFICATION forming part of Lettrs'ratentivo; 259,211, dated Junee, 1882.

Applicationiled March '14, 1882; (o model.)

Beit known that I, JONATHAN B. RICHARDS, of Wager, in the county of Benton and State of Arkansas, have invented anew and.Improved Bench-Pin Attachment, of which thel following is a full, clear, and exact description.

The object of my invention is to provide a bench-pin to be attached to wood-workers benches which shall be adapted to be moved vertically and horizontally, for holding lumber lof different widths and lengths, and one which shall be adapted to be used with both high and low vises.

Reference is to be had to the accompanyingv drawings, forming part ofthis specification, in which similar letters of reference indicate cor; responding parts in all the igures.

. Figure 1 is a side elevation of a bench, showing the manner 'of using my new bench-pin. Fig. 2 is a perspective view oi the complete dev-ice removed from the bench. Fig. 3 is a sectional plan view taken on the linea: or, Fig. 2. Fig. 4 is' a front elevation of the attachment for holding the work for elevated vises; and Fig. 5 is a sectional elevation ofthe same, taken on the line y y of Fig. 4.

A is the frame of the device, which may be of metal or wood,xformed with the lip or projection a at its upper end and with -the crotch or saddle b at its lower end. The parallel bars d d of the frame are formed with the grooves f f, which constitute ways in which the block B moves, and in one side of the bar d are formed the Vratchetteeth g, with which the pawl F engages for holding the block B at any desired point of elevation in the frame. This bar d is also formed with the square holes or passages jj for the attachment to the frame of the elevated support shown in FigsA and 5.

H and I represent the pins upon which the lumber is to be placed, which are carried by the sliding block B. The pin His aplain pin, formed with the head lnand is held a little belowT the pin I in a plain hole made through the block, in which it tits loosely. The pin I is a screw-threaded pin, formed with the head i, and is held in a screw-tap made through the The bench D, with which my improved device is to be used,w'ill be formed with a groove or rabbet for the lip c to t in, as shown in dotted lines Iat in Fig. 1, and will be provided jWith; the rail 'J, which reaches from' leg to leg of the bench upon which the device rests and nieves, the upper edge of the rail being convex in form `for the'crotch b of the frame to tit upon, forholdingtheframein place in the bench and for permitting its free movement upon the rail to suit the. length of lumber to be worked.

In case the lumber to be worked is straight,

the pin-H will be used to support it, which will ofcourse be drawn out ot' the block a snitable distance to suit the thickness of the lumber; but in case the lumber is heut or warped the pin I will be used, the head of it being adapted to be screwed against the lumber for straightening itand for holding itagainst the side of the bench.

While the pin H is being used the pin I may be entirely uuscrewed from the block and laid away; or it may be screwed into the block so far that it will not interfere with the use of the pin H. Y

The pawl F is pivoted to the block B upon the pivotj below the pins H and I, as shown, and it is so formed that the part of it above the pivot is ot' greater weight than the part be- The grooves ff in the bars d d', in which' the block moves, are triangular in form, and the edges of the block are beveled to lit the grooves, as is clearly shown in Fig. 3. This formation of the edges of the block and the groove is notvessential, however, to the device, as the block may be formed with plain tongues and the bars with plain grooves and accomplish the same end; but the form of tongue and groove shown is a cheaper construction, and is therefore preferred.

In case the device is to be used with an elevated vise, the elevated support J is to be used, which is formed of the sleeve 7c, having the lateral arm 7c and the adjustable T- bar I,

IOS

which is held in the sleeve k by means of the removable Wed ge or key n. The T- bar yis formed upon one side with the notches o, and the wedge or key n is formed with the head n', and the projection or lug n upon its back, which ts in the notches o of the T-bar, as shown clearly in Fig'. 5.

In order to attach the elevated support J for use, the arm le is to be placed in one or the other of the square holes j in the frame d', which arm is of sufficient strength to support the work. 'Iho T- bar l is then tobe adjusted the proper height by raising the bar and placing the lug n in one or the otherof the notches o of the bar, which will hold the har at the height desired.

With this construction it will be seen that the device, with its attachment, is a complete tool for its purpose, adapted to be used with both high and low vises, and is cheap and simple.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination ot' the frame A, having 25 JONATHAN B. RICHARDS.
